The problem lies in my actual file names and the way the column variable is assigned. I have a couple types of file formats unfortunately...

Type 1 = combinationoftextnumbersandcaharacter.fileextension
Type 2 = combinationoftextnumbersandcaharacter.combinationoftextnumber
+sandcaharacter.fileextension

In either case, only the first block is needed. The second block in Type 2 can be ignored as well as the file extension for both.
I'm going to look at regular expressions and try to make that work.
